Unlimited Dossiers
Local calculation of SHA-256 digests, Merkle trees, and deterministic manifests for files, folders, and archives.
Ilion product
ProofBundle
Verifiable technical evidence for digital works and files.
ProofBundle creates a portable cryptographic dossier locally. The original work stays on your device while the manifest, Merkle root, signature and timestamp enable independent verification.
Professional Evaluation Version
Available for forensic consultants, law firms, creative agencies, and studios. Includes the standalone CLI for your OS and generation of up to 3 official proof certificates (PDF).
3 Certificates Included
Generation of formal cryptographic proof certificates in PDF format ready for forensic audits or contracts.
Zero-Knowledge
No cloud upload: your work and proprietary files remain 100% strictly on your local machine.
What it does
Files, ZIP archives and complete directories
Deterministic manifest and Merkle root
Signed Ed25519 or OpenPGP claim
Optional OpenTimestamps timestamp
Offline verification of the dossier and work
How it works
- Create the dossier on your computer
- Store the work, key and evidence separately
- A recipient can verify integrity and signature
Concrete value
It can document existence, integrity, temporal priority and a signed claim associated with the work.
Stated limitations
It does not by itself prove originality, authorship or legal ownership. It does not replace copyright bodies, public registries, contracts, official deposits, courts or legal advice.
Official Documentation
Read the comprehensive reference covering all CLI commands (create, verify, cert, info, diff, keygen, ots), Merkle tree, Ed25519/PGP signatures, and Bitcoin timestamping.

ProofBundle
A file can be copied, renamed or changed without leaving an obvious history. ProofBundle fixes its cryptographic fingerprint, organizes multiple items in a deterministic manifest and associates a signed claim. Verification remains repeatable without depending on an Ilion server.
Practical use cases
- Delivering photographs, illustrations, manuscripts or audio files to a client
- Preserving approved versions of a creative project
- Technically documenting files delivered, received or archived
- Checking later that a directory has not been altered
What you receive
A portable dossier containing a manifest, hashes, Merkle root, signed claim and, when requested, OpenTimestamps evidence. The verification procedure is documented and can also run offline.
ProofBundle
For creators, studios, agencies and professionals who need durable, verifiable technical evidence.
